COMBINED ALTERNATE-CURRENT AND STORAGE SYSTEM OF ELECTRICAL DISTRIBUTION.

SPECIFICATION forming part of Letters Patent No. 383,623, dated May 29, 1888.

Application filed February 25, 1888.

T aZZ whom it may concern:

Be it known that I, HENRY M. BYLLESBY,

a citizen ofthe United States, residing in Pittsburg, in the county of Allegheny, in the State of Pennsylvania, have invented certain new and useful Improvements in a Combined Alternate Current and Storage System of Electrical Distribution, (Case 167,) of which the following is a specification.

The invention relates to an organization of circuits and apparatus whereby currents from a storagebattery may be conveniently employed for operating translating devices connected with a system of alternate-current electrio distribution.

The object of the invention is to provide convenient and eflicient means whereby currents from any convenient source of electricity may be employed for charging a storage-battery, and to utilize the currents from the battery in operating a system of electrical distribution employing alternate, intermittent, or pulsatory electric currents.

The invention consists in employing, in connection with a suitable source of electricity, a storage-battery adapted to be connected with the source at such times as required, and a rheotome or circuitcontrolling device whereby the currents from the storage-battery may be rendered intermittent, alternating, or pulsatory, as desired, for supplying the distributing system.

Certain other organizations of storagebatieries with systems of electrical distribution 5 are claimed in applieationsfierial Nos.251,199 and 251,200 and 251,198, dated October 1,1887.

In the accompanying drawings there is illustrated in diagram,in Figure 1, ageneral organizationof circuits and apparatus for carrying out the invention. Fig. 2 illustrates acircuitcontroller or rheotome in detail. Fig. 3i1lustrates a modification.

Referring to the figures, A represents a source of electric currents, and it may be any 5 suitable form of direct-current machine or a battery of sufficient capacity. The respective poles of this source are connected, by means of switches S and S with the poles of astoragebattery, B. This is of any convenient size or 0 number of elements arranged in any well- Serial No. 65,265. (No model.)

known manner for charging. Conductors b b are arranged to be connected in this instance with the respective terminals of the storage-battery B, for the purpose of discharging the battery into the translating system to be described.- Switches S and 8* are employed for controlling the connections. As here represented,switches S and S are opened and switches S and S are closed.

The work-circuit 7 consists in this instance of translating devices d (1, arranged in the secondary circuits of converters C and C These converters here consist of secondary coils, s 8 connected through the translating devices (I (Z, and ofprimary coils,pp'-,arranged in multiple are between conductors L and L The coils are wound on cores 0. It is desired for this system of distribution that intermittent, alternating, or pulsatory electric currents shall be employed upon the lines L and L for the purpose of operating the converters and producing the requisite currents in the secondary circuits. The invention is especially applicable to those systems in which currents of high potential are employed upon the pri mary circuit, L L and currents of a lower potential for operating the translating devices (1 d. In order that the direct currents from the storage-battery may be employed for thus operating the converters, and through them the translating devices, it becomes necessary to provide some means for changing the direct current from the storage-battery into intermittent, pulsatory, or alternating currents. The device D, here shown for that purpose, consists of a rheotome adapted to be revolved at a high rate of speed in any convenient manner-as, for instance, by an engine or by an electric motor, E, driven by currents derived through conductors c e from the storage-battery, or from any other convenient source. This rheotome here consists of two contact rings or plates, (1 at, having teeth or plates d d alternating with each other. The conductors b b are connected with the rheotome through brushes f f which rest continuously upon the respective rings, While the conductors L L are connected with brushes t and i which make alternate contact with the two plates through alternating teeth. In this man- IOU ner alternating impulses will be transmitted upon the lines L and L and these will beconvented into secondary or induced currents, which may be employed for operating the translating devices or for operating any system of alternating or secondary electric distribution. Direct-current machines or apparatus may be driven by currents derived from the generator Afor instance, electric motors-as shown at E E.

In some instances it may be desired to employ intermittent or pulsatory electric currents upon the line L and L In Fig. 2 there is shown a rheotome, D, adapted to render the current from the battery B intermittent. This is accomplished by connecting one terminal of the battery B, through the conductor 12', with a brush, f resting upon a conducting-ring, d". This ring has interposed plates d? of non-conducting material, which pass bencath the brushf as the ring revolves. The line L is connected with the ring d through the brush t. The line L is connected with the conductor b leading from the remaining pole of the battery. The rheotome is revolved as in the former instance.

In case pulsatory currents are required the device illustrated in Fig. 3 maybe employed.

This consistsin employingtwo insulated plates or rings, d andd", and the two brushes f and connected as before. The brush i makes contact with the two rings alternatelythrough the teeth d and (2 The plate (1 is connected with the plate d or the line L through a resistance, B, so that the resistance is alternately introduced into and Withdrawn from the circuit, thus causing a pulsatory current.

I claim as my invention The combination of a source of electricity, a storage battery, means for charging the same from said source, a rheotome for transforming direct into alternating, intermittent, or pulsatory currents, an electric motor operating the same, driven by currents from the storage-battery, an alternatingcnrrent system of distribution and translation, and switches whereby said system may be connected through said rheotome with said source.

In testimony whereof I have hereunto subscribed my name this 19th day of January, A. D. 1888.

HENRY M. BYLLESBY.
